The principle of surfactant oxygenation: adding surfactant to aquaculture water can increase the saturation solubility of oxygen in aquaculture water. According to hydrate formation theory and double membrane theory, because the solubility of oxygen in water is very small, water oxygenate usually forms at the gas-liquid interface, and then slowly diffuses from the gas phase to the liquid phase. In the water containing surfactant, due to the solubilization of surfactant, a large amount of oxygen is dissolved in the surfactant micelles formed in the aqueous solution. Thus, the formation of water oxygenates in the surfactant aqueous solution can occur not only at the gas-liquid interface, but also within the water body, which reduces the formation time of water oxygenates and improves the oxygen content in water Solubility in.   

Flame retardant is a functional assistant that gives flammability to flammable polymers. It is mainly designed for the flame retardancy of polymer materials. There are many types of flame retardants, which can be divided into additive flame retardant and reactive flame retardant according to the use method. Additive flame retardants are added to the polymer by mechanical mixing method to make the polymer have flame retardancy. At present, the additive flame retardants mainly include organic flame retardant and inorganic flame retardant, halogenated flame retardant (organic chloride and organic bromide) and non halogen.

Polymer surfactant not only has excellent emulsifying stability, but also can give the emulsion special properties, which is incomparable with ordinary surfactants. Polymer surfactant has a strong emulsifying ability. When a certain amount of graft copolymer is dissolved in oil (water), the oil-water system will be emulsified and the emulsion will be stable after sufficient oscillation.

China has become the world's largest consumer of chemicals, and a large number of chemicals are used in all kinds of industries. Basic chemicals and special chemicals have vitality and development potential in the chemical industry. In order to promote the rapid development of basic chemicals and special chemicals industry, accelerate the popularization and application of products, and strengthen the exchange and cooperation between industries.

The three biosurfactants have different removal effects on heavy metals: 0.5% rhamnolipid has a better removal effect on Cu with a removal rate of 65%; 4% sophorite has a better removal effect on Zn, which is 60%; while safantin has no significant effect on both, the removal rates are only 15% and 6%. The changes of speciation of heavy metals in sediments were also studied. Rhamnolipid and savantoin mainly removed organically bound Cu, and sophorite mainly removed oxide bound and carbonate bound Zn. This study also confirmed that the method of washing sediment with biosurfactant to remove heavy metals is feasible.

Generally speaking, biosurfactant has excellent performance in pollution control. Due to the strict requirements of biosurfactant production conditions such as temperature and pressure, the product extraction is difficult, and the separation and extraction of tile products and the purification process of crude products are complex. Therefore, the scale of biosurfactant fermentation production in China is small and the product price is high. Therefore, the cost and other parties are considered Surface factor biosurfactants have not been widely used in soil remediation.

Human concern for waste plastics began in the 1960s. However, due to the rapid growth of waste plastics in the past 30 years, it is urgent to recycle and reuse waste plastics. Therefore, some developed countries have formulated relatively perfect policies and regulations and established effective recycling and reuse systems. According to statistics, the recycling of waste plastics has become an urgent task In Europe, for example, the recycling rate is 11%, 21% is burned and 14% is transported abroad for treatment.

Surfactants with excellent properties have become the focus of research. Gemini surfactants are compounds with two hydrophobic groups, two hydrophilic groups and one linker, which are similar to two common single chain surfactants connected by a bridge. The structure of Gemini surfactant inhibits the repulsion between hydrophilic groups in the process of surfactant ordered aggregation, which greatly improves the surface activity. Compared with traditional surfactants, it has high surface activity, low Krafft point and good calcium soap dispersion, and simultaneous interpreting in biological safety, low irritation and biodegradability. Gemini surfactant is expected to play an important role in textile industry, especially detergent.   

Petroleum composition is often very complex, and this complexity is often interwoven with the complexity of structural components of contaminated soil, resulting in the complexity of pollution characteristics and consequences.

In the past two years, the Ministry of science and technology of the people's Republic of China, two major oil companies, PetroChina and Sinopec have organized a series of research projects on surfactant compounding, and organized large oil fields, scientific research institutes and universities to carry out a series of research projects, and achieved some basic research results. In the surfactant flooding system of Zhongyuan Oilfield, Changqing Oilfield, Dagang Oilfield and Yanchang oilfield, several low permeability reservoirs have been selected for field test, and the effect of EOR is obvious. In Zhongyuan Oilfield, the displacement efficiency of composite surfactant in formation water is 7.68% higher than that of petroleum sulfonate. Shengli Oilfield developed a low-cost composite surfactant for oil displacement in Zhuangxi area with high temperature and low permeability. The exploratory application test of the agent was carried out in No.5 zhuangzang 50 well group in 2006. As of May 2007, the oil production of 6 wells in this well group increased by 1656 tons.   

Surfactants can also be used as dispersant, wetting agent, foaming agent, crystallization control agent, bactericide and so on in food production, and also can prolong the fresh-keeping period of food.

Surfactants are one of the main components of detergent detergents. Except for special purposes, these products are discharged into the environment directly or after being treated by sewage treatment plants. However, anionic surfactants, which are difficult to biodegrade, play an important role in detergents. The discharge of surfactant containing wastewater not only directly harms the aquatic environment, kills microorganisms in the environment, inhibits the degradation of other toxic substances, but also leads to the reduction of dissolved oxygen in water, especially the nitrogen and phosphorus containing surfactants will cause eutrophication of water. When the concentration of surfactant in wastewater reaches a certain concentration, it will affect many processes such as aeration, sedimentation, sludge nitrification, etc.

A new type of polyol type non sucrose fatty acid esters (SE) is a new type of polyol non-ionic surfactant, which is white or yellowish brown powder, block or yellowish viscous resin. Since the hydrophilic lipophilic equilibrium (HLB) of sucrose fatty acids does not change with temperature, the range of HLB is wide (1-16). Sucrose ester can be used not only as w / O emulsifier, but also as O / W emulsifier. Sucrose ester has good emulsifying, dispersing, solubilizing, penetrating, foaming, viscosity adjusting, anti-aging, antibacterial and other properties. At the same time, it is non-toxic, especially safe to human body, non irritating, degradable, and will not cause environmental pollution. Due to its excellent characteristics, sucrose ester is widely used in food, chemical industry, cosmetics, etc Oil mining, fruit preservation, textile and agriculture industries. Se is a food additive and medicinal material recommended by FAO and who. China also approved the use in the 1980s.

The use of surfactants alone has little harm. There are two reasons for the damage to crops caused by surfactants in pesticides. One is that surfactants increase the solubility of drugs, and the other is the effect of surfactants on crops. For example, after spraying wheat chemical hybrid agent genesis, there is burning phenomenon on the last two leaves of plants.

Surfactant in pesticide is one of the indispensable components of pesticide preparation which can not be used directly. It can not only improve the use effect of pesticides, but also reduce the amount of pesticides, reduce the impact of pesticides on the environment, and bring great benefits to agricultural production.

Polyether amine in the production or transportation storage, for each step of the operation requirements must be accurate, not sloppy, then the above on the chemical safety technology knowledge, I hope to help you.

The application of surfactants in leather production has broad prospects, but there is still a certain distance from surfactants to leather additives. How to use surfactants skillfully in leather production requires the combination of surfactant researchers and Leather Technologists, starting from the characteristics and needs of leather processing, to do in-depth and detailed research. However, with the progress of society, environmental protection is more and more advocated and valued by people, and the development of leather industry is bound to be challenged. Therefore, it is very urgent to develop and research new surfactants for leather production.

The fabric itself is easy to ignite and burn, so in order to increase the safety, it is necessary to add flame retardant into the fabric after processing. In this way, once the fire occurs, the fire will not be intensified immediately, and it can be effectively isolated.

At present, flame retardants are mainly divided into organic, inorganic, halogen-free and halogen-free. Among the organic flame retardants, brominated flame retardants have some advantages in many aspects, but they have been hotly discussed by environmental protection experts. In halogen-free flame retardant system, red phosphorus can be regarded as an excellent role, with the advantages of less addition, good flame retardant effect, wide application range and good environmental protection effect.
